Selecting dimethyl silicone oil depends on the application, especially viscosity, purity, temperature range, compatibility, and electrical requirements.
Dimethyl silicone oil has a high level of safety within compliant limits, but food and medical uses require strict purity, grade selection, and regulatory compliance.
Dimethyl silicone oil, or polydimethylsiloxane, is widely used because of its broad viscosity range, stability, insulation, water repellency, and lubricity.
